This is starting to repeat like a broken record ... From Spaceflight Now, yet another Dragon delay:
The target launch date for SpaceX's first test flight to the International Space Station is now no earlier than late April, the company announced Thursday, as the California-based firm and NASA continue extensive software testing to prove the Dragon spacecraft can safely approach the 450-ton orbiting complex.
"SpaceX is continuing to work with NASA to set a new target date for launch, expected to be late April," SpaceX said in a statement. "The primary driver for the schedule continues to be the need to conduct extensive software testing. This is a challenging mission, and we intend to take every necessary precaution in order to improve the likelihood of success."
